to frictionally engage the stop-pins. If desired, the stop-pins. may be provided with. grooves to receive the ends of the springs, which will prevent said stop-pins from being shot out of the apertures in which they are seated, the grooves being of sufficient width not to interfere with the movement of the p ns.

Upon the base-board A is mounted a standard'which carries a bell-crank lever D, and said lever has its upwardly-projecting memher cut away or shouldered to terminate in an anvil or hammer d. Adjoining this bellcrank lever is a stop-block D. The bellcran'k lever and controlling-wheel operate in unison, as when one of the stop-pins is pushed inward the projecting end thereof will abut against the stop-block, and thus limit the rotation of the spring-driven shaft, and when the horizontal member of the bell-crank lever is depressed the shoulder thereof will pass between the projecting arms or members of the controlling-wheel, a-further depression causing the hammer or anvil end (1 to strike against the projected pin of the controllingwheel and push the same out of engagement -with the stop-block; When the bell-crank lever is'released, the upper member thereof will be moved out of the path of the controlling-wheel and said controlling wheel' will i turn, being actuated by the shaft until. it-is stopped by the stop-pin that has, been pro.-

jected by the operation of a key-lever,

as hereinafter described. This controllingwheel,in connection with the bell-cranklever,

may be applied to many styles of registering mechanisms and forms, per se,.a distinctfea: ture and complete invention.

E designates the key-levers, a. series. of nine levers being pivoted on a cross bar mounted between the frames A. and A and these key-levers. pass through a slottedfaceplate and terminate so that the keys will be arranged in two banks, preferably four in the upper and fivein the lower, as shown. The key-levers are provided with springs e for holding, their forwardends normally raised". The key levers are connected by rods 6 tea series of levers-E, which are joun naled on a transverse shaft or support e in the upper part of the frame A, and these levers extend toward the frame A, crossing considerably above the key-levers and at right angles therewith, the free ends entering vertical slots in a plate E carried by the frame A. Each lever E has formed integral therewith a depending member E, said memhere being of different lengths and curvatures, so that when actuated, they will contact with the headed ends of the stop-pins. It will be noted at this point that there are nine keys for operating nine levers, each lever having a depending member which is adapted to contact with the stop-pins, the

ends of said depending members being in the path of but nine of the ten sto -pins, as one of'said stop-pins is supposed to sin engagement with the stop-block. It will also be noted that each of the nine keys hasan equal amount of depression, each being supported in the same manner, performing the same work, and therefore having an equal touch.

Beneath the key-levers E is a. frame F,

preferably journaled on the same shaftwith the key-levers, and said frame is provided with a transverse portion with which the key levers engage. From the center of the transverse portion of the frame F projects a memberf, the end of which engages a slot in the horizontal member of the bell-crank level-D, hereinbefore referred to. The frame F is .held normally raised by a spring-actuated plunger F, which enters a. suitable socket,

as F mounted on. the base-board A and con,- taining a. helical spring. When any one of the key-levers is depressed, the frame F is moved downward an d operates the bell-crank 'lever to movethe vertical member thereof toward the controlling-wheeh The features of our invention that have been so far described may be applied to, any calculating or, registeringmachine to which: it may be adapted, irrespective. of the construction of'the digit-wheels orequivalent mechanism.

The shaft B, which is connected bya trai means of a link i, 'to.a bar K, which bar is pivoted at one end tothe lower portion; of the frame A and engages with a cipher or zero key pivoted adjoining theframe A the forward portion of said key passing through a slot, in the frame. By depressing-the cipher or zero key the dog will be released fromthe rack-bar J, so the carriage can move, a distance of one notch to permit the gear-wheel thereon to engage the next digit-wheel, andin its movement the upwardly-projecting member H of the carriage elevates the locking-pawl that is in engagementwith. said digit-wheel, The carriage is automatic in its action and is drawn toward the end of the machine having the key-levers by means of a flexible connectioii which passes around a spring-actuated. drum S, over a guide-pulley s, and is attached to the dog-I, as shown".
